Abstract

Chlamydia abortus (C. abortus) is a Gram-negative intracellular bacteria responsible for major economic losses due mainly to infection and subsequent induction of abortion in several animal species and poses considerable public health problems in humans. This study was conducted to determine the prevalence of antibody against C. abortus in sheep and goat population of Khorasan Razavi province located in northeastern Iran. Four hundred fifty-two (271 sheep and 181 goats) sera samples from 40 sheep/goat epidemiologic units located in 11 counties were selected. Sera were assayed for antibodies against C. abortus using ELISA assay. Out of 452 sheep and goat sera, 44 [9.70% (95.00%CI: 7.10%-12.40%)] were positive for C. abortus antibodies. 28 out of 40 epidemiologic units (70.00%) and 10 out of 11 counties (91.00%), at least one seropositive sample was found. There was no significant difference between the seropositivity of sheep and goats. Age, sex, and location did not show significant relationship with the test results. The results showed that C. abortus was circulating in wide parts of Khorasan Razavi province. Considering the economic and public health importance of C. abortus, measures should be taken to help prevent its spread and to reduce the zoonotic risk of C. abortus in the studied region.
